North Anna, Paducah, Japan

Yoshihiko-Noda-REUT_641302tJust to cross a T from last week’s earthquake:

Dominion, the plant's operator, notified the NRC Friday that its analysis of ground shaking showed the quake could have exceeded its design parameters. An independent analysis by the government also had determined that was likely.

Oh?

But since nuclear power plants are built with margins of safety beyond the maximum expected shaking, the damage detected so far has been minimal.

Oh!

The NRC had already sent a seismic expert and a structural expert out to the facility, in addition to its inspector onsite.

Let’s keep on eye on this one and see how it shakes out.

The Paducah (Ken.) Sun looks at both North Anna and Nebraska’s Fort Calhoun (which found itself in the middle of a swollen Missouri River during much of the summer) and notes that both came through their respective bouts with mother nature unscathed. Conclusion:

With debate growing more intense over the safety of nuclear power as part of the U.S. energy picture, these two unplanned tests of nuclear reactors are instructive. Especially in light of the March 11 earthquake in Japan that provided fodder for opponents of nuclear energy.

The performance of the nuclear plants at Fort Calhoun and North Anna demonstrates that nuclear power generation can be safe, economical and reliable.

Well, safe in these situations is the one to note and the plants did do reliably what they’re supposed to do when the ground shakes or the water rises. They’re economical all the time – it’s a gimmee in this context. We’ll take it.

Japan's parliament has backed Yoshihiko Noda as the country's sixth prime minister in five years.

I cannot pretend to understand Japanese politics, but I think I can grasp the revolving doors at the prime minister’s residence:

An earlier agreement to raise taxes to cover welfare costs was a good start at fiscal consolidation, but the best chance for success is a stable government, Byrne added.

Japan's next leader has a mountain of challenges ahead, from battling a soaring yen and forging a post-nuclear crisis energy policy to rebuilding from the tsunami and reining in public debt, while paying for reconstruction and the bulging costs of an aging society.

The March disasters knocked the economy back into recession, and the strength of an expected rebound later this year is being clouded by weak domestic and global demand and recent gains in the yen, which threaten export competitiveness.

This story from Moodys is largely about its investor service cutting its rating on Japan’s debt. But Japanese Prime Ministers seem much more likely to throw in the towel before their terms are up than, say, American Presidents or British Prime Ministers. That leads to instability – even if the ruling party remains the same – while a new Prime Minister assembles his staff. I imagine there are a lot of people coming and going in the ministerial jobs. Although Japan does not appear to be in a political state of crisis, it makes Moodys nervous.

The BBC included this tidbit:

Unlike Mr [Naoto] Kan [the former PM], he [Noda] wants Japan's halted nuclear reactors to be restarted and has not backed his call for a nuclear-free Japan.

So there’s that. We may feel this is the best thing for Japan to do, especially as it will suffer a pretty rough winter without the reactors, but how it goes for nuclear energy in Japan will likely not be determined for some time. Kan was reacting to public opinion perhaps a little precipitously, but Noda will take account of it too – and the opinions of his ministers – and the options open to Japan in the electricity sphere.

So we can agree with Noda’s current views without necessarily expecting they will remain unchanged – or that Noda will retain his position where his predecessors did not – or without imagining that anything is settled about the future of nuclear energy in Japan.

Japan Prime Minister Yoshihiko Noda.

Actually, I am living in Japan, the peak is summer, so no rough winter to foresee. The problem is that the halted reactors and their fossil fuels counterparts cost a lot, which is damaging the recovering economy. Hence Noda's reaction.

A Design Team Pictures the Future of Nuclear Energy

For more than 100 years, the shape and location of human settlements has been defined in large part by energy and water. Cities grew up near natural resources like hydropower, and near water for agricultural, industrial and household use.

So what would the world look like with a new generation of small nuclear reactors that could provide abundant, clean energy for electricity, water pumping and desalination and industrial processes?

Hard to say with precision, but Third Way, the non-partisan think tank, asked the design team at the Washington, D.C. office of Gensler & Associates, an architecture and interior design firm that specializes in sustainable projects like a complex that houses the NFL’s Dallas Cowboys. The talented designers saw a blooming desert and a cozy arctic village, an old urban mill re-purposed as an energy producer, a data center that integrates solar panels on its sprawling flat roofs, a naval base and a humming transit hub.

In the converted mill, high temperat…

Sneak Peek

There's an invisible force powering and propelling our way of life.
It's all around us. You can't feel it. Smell it. Or taste it.
But it's there all the same. And if you look close enough, you can see all the amazing and wondrous things it does.
It not only powers our cities and towns.
And all the high-tech things we love.
It gives us the power to invent.
To explore.
To discover.
To create advanced technologies.
This invisible force creates jobs out of thin air.
It adds billions to our economy.
It's on even when we're not.
And stays on no matter what Mother Nature throws at it.
This invisible force takes us to the outer reaches of outer space.
And to the very depths of our oceans.
It brings us together. And it makes us better.
And most importantly, it has the power to do all this in our lifetime while barely leaving a trace.
Some people might say it's kind of unbelievable.
They wonder, what is this new power that does all these extraordinary things?

New Home for Our Blog: Join Us on NEI.org

On February 27, NEI launched the new NEI.org. We overhauled the public site, framing all of our content around the National Nuclear Energy Strategy.

So, what's changed?

Our top priority was to put you, the user, first. Now you can quickly get the information you need. You'll enjoy visiting the site with its intuitive navigation, social media integration and compelling and shareable visuals. We've added a feature called Nuclear Now, which showcases the latest industry news and resources like fact sheets and reports. It's one of the first sections you'll see on our home page and it can be accessed anywhere throughout the site by clicking on the atom symbol in the top right corner of the page.
Most importantly for you, our loyal NEI Nuclear Notes readers, is that we've migrated the blog to the new site. Moving forward, all blog posts will be published in the News section, along with our press releases, Nuclear Energy Overview stories and more. Just look for the &qu…
